Hi There

I am trying to create a looping particle animation and there seems to be a weird delay in the beginning of animation. I have reduced my data to 1 point and 10 frames and created a super simple position sampler, but the problem still presists.
In Particle Update my ‘Test Script’ just reads the position value of the particle 1 at frame 1 (the position is 0,0,0 here) and passes it on to the Houdini particle position parameter. But I have to go to approx. 0.03 on the timeline before the particle shows up.

WHAT am I not understanding here?!?

Cheers

Thank you both of you for the answers.
I ended up using the pythonexprs solution but tested out the JSON one too just to learn some more :-)
one (unrelated) question zengchen, is there a deeper meaning why you use a string parameter ( ) instead of just directly using a string in ? just curious :-)

As the title says, I am trying to use a key-value dictionary parameter to drive another parameter via an expression but I can't seem to make it work?


I haven't been able to find any information regarding this, I'm afraid.

Cheers
